Ecumenical Patriarch Photios

Ecumenical Patriarch Photios (820-2 June 893) was the Ecumenical Patriarch of Constantinople from 858 to 867 and 877 to 886, succeeding Ecumenical Patriarch Ignatios both times and preceding Ignatios and Ecumenical Patriarch Stephanos I.

Biography
Photios was the most powerful and influential patriarch since the death of John Chrysostom, and he converted Slavs to Christianity. During his reign from 868 to 867 he replaced Ecumenical Patriarch Ignatios at Michael III of Byzantium's request, but in 867 Basil I of Macedonia restored Ignatios. When Ignatios died in 877, Photios succeeded, and he was the Patriarch of Constantinople until his death in 886.
